Commissioning
It is essential that all new pipework installations are purged and tested for soundness using a suitable leak
detection fluid prior to attempting to ignite any appliance. This work should be carried out in accordance with
National or Local Regulations.
N.B. DO NOT TEST FOR SOUNDNESS BY USE OF NAKED FLAMES
.
5.1.
Ignition
.
5.1.1. Turn on the gas supply to the appliance.
5.1.2.
Switch on the electrical supply to the appliance.
5.1.3.
If the appliance has a thermostat fitted in the electrical supply circuit, ensure that it is set high enough to
demand heat.
5.1.4.
After a waiting time of 1 second, the solenoid valves and the spark ignition electrode will be energised
simultaneously.
5.1.5.
Upon successful ignition the flame will be detected by the flame sensor and the ignition spark electrode will be
de-energised.
5.1.6.
Should the flame fail to permanently establish during the 25 seconds ignition period (Honeywell Control) or 10
seconds (S.I.T. Control) the solenoid valve and ignition spark electrode will be de-energised and the appliance
Ignition Control will go to "lockout" condition.
5.1.7.
To repeat the ignition sequence it will be necessary to switch off the electricity supply to the appliance for a
period of 10 seconds to reset the ignition control. If a first reset is not successful, wait at least 15 seconds
before repeating the procedure. After reset, an extended waiting time will occur.
5.1.8.
If the burner fails to ignite following a second ignition sequence, turn off the gas supply at the gas isolation valve
and investigate the fault.
5.1.9.
If gas failure occurs after successful ignition the appliance ignition control will attempt one re-ignition before
going to "lockout" condition.
5.2.
Shut Down
5.2.1.
To shut down the appliance for short periods of time, switch off the electrical supply to the appliance.
5.2.2.
To shut down the appliance for a period of time in excess of one week, switch off the electrical supply to the
appliance and turn off the gas supply at the gas isolation valve.
Note
: concise operating instructions are contained on Instruction Label (4260460), which should be affixed
adjacent to a low-level user control.
